' Econ-GRINDING mavIcE..A

To all whom t may concern:

Be it known that we, JACOB L. BAUER and' ROBERT BAUER, both citizens of the United States, Vand residentsof Milwaukee,'in the y county of Milwaukee and State of Wisconsin, have invented certain new and useful 'Improvements inl Food-Grinding ,Devices and we do hereby declare that the following isv .a rfullclear,- and exact description thereof. g, t A w Our. "vention relates to newand useful improvements in devices for comminuting food material, more particularly of that type disclosed in our copending application for patent iiled `Ma`rch th, 191,9, VSerial N o. 284,945, adapted Vfor household'use and comprising a main cylinder with which isv associated I a reciprocative cutter member movableacross one end of the cylinder.

It is the-object:V of our present invention to' rovide anarrangement in connection wit said main kcylinder Afor carrying ,out

Y the Operation of grinding meatfor other relatively tough food material wherein the food .material 'is forcibly mechanically fed toward the cuttingmeans.

It is more particularly our Object to prog.

vide a selfcontainedgrinderunit which mayy be `readily associated with or -detached'from i" thecylinder and which utilizes the cylinder.-

asa support means. 2

further'object resides 1n a' provision vOfa unit of'this character which isof eX- ceedingly simple construction Yand Awhichy may be readily assembled and disassembled for theV frequent cleaning operations necesl sary; in the `use. of devices of this char-V acter'.'v

With the above and other objects and advantages in view, our invention" resides in the Vnovel combination, formation and arrangement of parts hereinafter more ,fullyv describedand particularly' pointed out in theY appended claims. A-

In the accompanying VVdrawings i.

Figure l1 is a vertical sectional viewV through a food our invention. t Y v Fig. Qis an elevational view of the discharge end portion. i' .Referring accompanym drawings, number 5 designates the horizontally extendin feed cylinder of the food comminuting evice shown in our `said co-pendingl application, this grinding device embodying now more particularly to the,

ciprocative cutter member driven from a Specification of Letters :Patenti Patented Dec, 9 1.919, f Applicationmea my 5,1919; semaine. 294,909. Y y

-. cylinder having a track "wall 6 at one end and being'supported at said end in spaced relation to 'astandard by studs 8 project- .lng from the standard atthe sides of the cylinder, the standardv affording 'a Vfixed support for the device land the `cylinderA` track wall 6 being adapted to mount a recrank shaft Ywhich is journaled in a bearing 9 Von the standard, said shaft andV` cut-l ter member vbeing removed in the Vuse of the. grinder unit comprising vthe subjectmatter of the present application. The feed cyl-V inder 5 is provided lwith an"intermediateV `S}1pply hopper 10 andhas'its 'free end por-y tionglared, both open.

The grinder unit comprises an irmer cylends,` of the cylinderV being inder llfwhich isslightly smaller in external diameterthan the internal' diameter vof the '75 c'ylinder vand which is adaptedv to beslid Y @into the cylinderz 5,' one end-.of the cylinder f 11'being providedfwithj a-series ofoutstanding `lugsk 13` which r`are'machined tof form 'anjgV .accurate fitl lagainst the periphery fof the cylinder 5 at Vits Yinner end. The vother end of the cylinderll` provided with an outstanding annular flange fitting in' the outerv end of the: cylinder 5 and'prov'idedwith re` cesses 14 for Vregistry with the holding lugs 15 on the cylinder 5 which, asV more particule i larlysetl forth in our said copending-appli-- cation, are adapted to hold a follower member against accidental inovementfrom'the cylinder', this follower member being removed in the use of the present grinder'unit. The inner cylinder 11 1s providedwithl an inlet openin 16 inregistry with the discharge mout of the supply hopper 10, and the outery periphery of the cylinder- 11 is provided vwith an outstanding rib 17 sul'- roundingI thev opening 16 to yclose the space between the-cylinders. A. feed wormV 18, of the type common to meat rinders, is rotatably disposed in the cylin erv 11, this worm having an'annular liange 19 on one end in peripheral bearing engagementwith the inner end of the cylinder 11 ,and in end-thrust bearing` engagement with an in- Wardly extending annular `iange 2O zformed in saidcylinder adjacent its inner' end. A shaft section 21 extends from the worm and is journaled in the bearinV -9 ofthe standard, said shaft havin a s oulder 22 adapted to abut the standard. A

crank .han-A ofthe sha-ft section by a. wing nut 24C, VA

erforated )late 25 is dis aosed in the. outer end portion of the cylinder 11 and this plate is centrally apertured to form a journal for a shaft section 2G extending from the outer end of the feed wormi8, a lmife member 2'? being secured on said shaftiportion at the outer face of the plate and retained in place by a wing nut 28 threaded on the extremity of the shaft section.

A simple and complete arrangementv is thus providedv wherein all the parts are held in assembled operative position. The cylinder 11 is held against rotation by the lugs 15 and is held by the plate 25 and flange 19 of the worm against longitudinal movement in either direction, said worm being in turn held against longitudinal movement by the abutmentr of the shaft shoulder 22 and hub of the crank 23 against the standard bean ing 9. The grinding operation is carried out in the usual manner by rotating the worm 18 tol force the food material through the apertured. plate ,25 from which the material is removed by the shear action of the radial blades of the grinder unit may be removedby simply removing the wing nut QLland allthe parts of the grinder unit` may be Vmutually disassembled by removing the Wingnut 28.

By the arrangement described, the cylinder andrsupport standard of the device -shown in our copending application are utilizedto operatively mount a grinder unit.

wWhile we have shown and described a preferred embodimentl of our invention, it will be appreciated that various i changes and modifications of structure may be employed to meet differing conditions of useiand manufacture without department in any manner from the spirit of our invention.
